Doesn't play nicely with SwiftKey

[gunar]

1. $|0.00 (| is cursor)
2. Type 555. On typing the third digit, format-as-currency adds the comma (,) which selects (makes selection) of the here-bold-text: '$5**,55**0.00'.

There is some issue with the decimals too.

This is probably out-of-scope but it could be thought of in the future. Mobile is taking over and SwiftKey is pretty popular.

Thanks.

that's pretty tough. if you want to detect the current cursor position and set the new one appropriately, feel free to make a pr. if there are other apps that manipulate the cursor, we can potentially make this behavior pluggable.
